This hole is usually closed w an aluminum pipe plug. Tank is aluminim.

I position and bend the copper tube so it's end is at the lowest point in the tank. I usually pump out about a quart of fuel into a semi-clear plastic jug. Hold it up where there is good light and look up at the bottom of the jug. Even small bubbles of water are very apparent. A few small bubbles is usually all I get.

I've never had any water in my Racor water trap.
This is a great way to handle it. You could also Tee into the pickup line going to the lift pump and add a large racor/pump that feeds back to the fuel tank. Simply recirculating for a few hours would pull almost all of the water out of the tank.
